Multiplexed Cell DIVE imaging of Adult Human Alzheimer’s Brain Tissue labelled with 15 antibodies targeted towards markers specific to astrocytes (GFAP, S100B), microglia (TMEM119, IBA1), and Alzheimer’s-associated markers (β-amyloid and p-Tau217).

Explore Alzheimer's Spatial Proteome with Big Data

Alzheimer's disease, a genetic and sporadic neurodegenerative condition, leads to cognitive decline in mid to late life, marked by β-amyloid plaques and tau tangles. With limited treatment options,…
Colon adenocarcinoma and normal colon at the tumor margin. 13 biomarkers shown including Cadherin, CD3, CD4, CD8, CD20, CD31, CD45, Collagen, Caspase 9, BCL2, Beta-Catenin, Vimentin, and Smooth Muscle Actin.

Uncover the Hidden Complexity of Colon Cancer with Big Data

Colorectal cancer poses a significant health burden. While surgery is effective initially, some patients develop recurrent secondary disease with poor prognosis, necessitating advanced therapies like…
Pancreatic Ductal Adenocarcinoma with 11 Aerobic Glycolysis/Warburg Effect biomarkers shown – BCAT, Glut1, HK2, HTR2B, LDHA, NaKATPase, PCAD, PCK26, PKM2, SMA1, and Vimentin.

Dive into Pancreatic Cancer Research with Big Data

Pancreatic cancer, with a mortality rate near 40%, is challenging to treat due to its proximity to major organs. This story explores the complex biology of pancreatic ductal adenocarcinoma (PDAC),…

Overcoming Challenges with Microscopy when Imaging Moving Zebrafish Larvae

Zebrafish is a valuable model organism with many beneficial traits. However, imaging a full organism poses challenges as it is not stationary. Here, this case study shows how zebrafish larvae can be…
Block-face created by automatic trimming under fluorescence. Mammalian cells of interest, stained with CellTrackerTM Green are visualized within the block-face using the UC Enuity equipped with the stereo microscope M205 FA. In the background a carbon finder grid in black is visible. All samples in the article are created by Felix Gaedke, PhD, CECAD, Cologne, Germany.

How to Automatically Obtain Fluorescent Cells of Interest in a Block-face

Block-face created by automatic trimming under fluorescence. Mammalian cells of interest, stained with CellTrackerTM Green are visualized within the block-face using the UC Enuity equipped with the…

The Polarization Microscopy Principle

Polarization microscopy is routinely used in the material and earth sciences to identify materials and minerals on the basis of their characteristic refractive properties and colors. In biology,…
Image of a 12-μm thick brain section, which was stained with Toluidin blue, before dissection. It was taken with a microscope using a 63x objective.

An Introduction to Laser Microdissection

The heterogeneity of histological and biological specimens often requires isolation of specific single cells or cell groups from surrounding tissue before molecular biology analysis can be carried…

Molecular Biology Analysis facilitated with Laser Microdissection (LMD)

Extracting biomolecules, proteins, nucleic acids, lipids, and chromosomes, as well as extracting and manipulating cells and tissues with laser microdissection (LMD) enables insights to be gained into…
Image of murine dopaminergic neurons which have been marked for laser microdissection (LMD).

Neuron Isolation in Spatial Context with Laser Microdissection (LMD)

After Alzheimer’s disease, Parkinson’s is the second most common progressive neurodegenerative disease. Before the first symptoms manifest, up to 70% of dopamine-releasing neurons in the mid-brain…
